FIELD: the invention refers to electric equipment.
SUBSTANCE: the arrangement for continuous measurement of a shaft deterioration by a stuffing box seal is fulfilled in the shape of a body with located inside it a primary and a secondary stuffing box seals , of a contacting with it hollow shaft with two brush contacts connected to a current generator, of a differential power amplifier and of a power source located in the cavity of the shaft. Additionally the arrangement is provided with yokes and pressure nuts for regulating the parameters of the stuffing box seals. At that inside the hollow shaft there are located in series a modulator connected with the output of the differential amplifier, a power amplifier, a light emitter and at a distance from the rotating shaft there are a photo receiver, an amplifier, a demodulator, an intensifier and a recording device located in series.
EFFECT: increases accuracy of measuring and reliability of the arrangement.
